OK, here is a strange DNS issue that is different. =20 Not sure if this is specifically a sendmail or bind issue or a FreeBSD issue. But when sending email to a domain that is LAME (e.g. supercom.ca = or beckett.com)) where the 2 authoritative name servers are giving non authoritative answers, I want to send mail to it anyways. Using the same rev of sendmail on a lINUX box works in conjunction with asking the = FreeBSD nameserver. Any idea why sendmail 8.11 on FreeBSD would be more strict than the same rev on Linux ? # name resolver options #O ResolverOptions=3D+AAONLY ResolverOptions=3D-AAONLY or ResolverOptions=3D Does not seem to have any effect.
